Gravity filter Polytech

Polytech’s gravity bed filters, which offer automatic operation and use low cost bulk roll filter media, are well suited to applications with moderate contaminant levels. Contaminated liquid flows through non-woven synthetic filter fabric supported by the conveyor belt. As filtered contaminants restrict the liquid flow, the liquid level rises and actuates a float switch which starts the conveyor. Unlike so-called “deep bed filters” which utilize a submerged edge seal to prevent contaminated coolant from leaking directly into the filtered coolant tank, the filter paper contains the entire pool of liquid and filter paper is transported beneath the liquid. You get reliable filtration without seal maintenance. Gravity filters are available as filter chassis only or fully outfitted with tank, pump and electrical controls.
